ST 2084 or Perceptual Quantizer is able to represent luminance levels of 300, 1000 and

Marker
Aspect ratio is a crucial element in video shooting and it is defined as the proportion of the width
and height of any image. You can use different aspect ratios in your video. Therefore, in order to
know what will be in frame at different aspect ratios, during shooting, you can turn on the TLM-
170F’s aspect marker (a.k.a. guide frame) so that you can record the entire screen while still
knowing where the cut-off will be by putting a mat over it.
